Abstract
An underwater laser source is used in water and comprises a water pressure-resistant cylinder A having a light emission window 4, and the water pressure-resistant cylinder A comprises a plurality of semiconductor lasers 11a-11f, and converging lens 13 that converges each laser light from the plurality of semiconductor lasers 11a-11f, and emits converged each laser light to the light emission window 4.
Claims7
An underwater laser source, that is used in water, comprising:
- a water-pressure resistant cylinder having a light emission window, wherein said water pressure-resistant cylinder further comprises:
- a plurality of semiconductor lasers;
- and
- a converging lens that converges each laser light emitted from said plurality of semiconductor lasers inside said water pressure-resistant cylinder, wherein said converging lens emits each converged laser light through said light emission window.
